Overlord

The skies darken as Harbinger enters a solar system, dwarfing planets and leaving devastation in its wake. Entire civilizations are cleansed, planets eliminated. The majority of the survivors fill the ship’s work camps. Those less fortunate are released to the laboratories where vicious experiments eventually rid them of their sanity. But a few have escaped and formed an underground society deep within the forgotten levels of the behemoth.
